KathyB......I'll through my two cents in. Buy one of the extendable poles with the soft touch brush end (it won't scratch your clear coat any more than any other item you rubber against your coach). Walmart sells them in their RV section. The brush is VERY soft to the touch. For years, I used Ivory dish soap to clean all of my vehicles, but found that the dish soaps were a little harsh. A few years ago I changed over to the car wash soap sold at Walmart. I believe its Meguairs (one gallon jug - gold).
Instead of pulling out a bucket like most do in the above posts, I fill an old dish soap bottle with the car wash soap. I wet down the side of the coach and then just squirt a line of soap on the wet car wash brush. One squirt usually washes about half of one side. I hit the brush with the hose, give it another squirt and keep working.
I hand dry my coach with old shower towels. I use a ladder and get as much as I can in an arms reach. If you don't want to use a ladder, take a push broom from your garage and drape a shower towel over it. Use the broom and handle to wipe the upper areas of the coach. After each wipe, slide the towel down farther on the broom head.
